To go along with the general trend here, I would like to state that all training isn't created equal. Military training included.
Some of the more egregious exampls of poor firearms handling I've seen came from the boys and girls in out S-1 and S-2 shops who got all the training they "needed" at Ft. Jackson.
Issues of trigger discipline, muzzle discipline, weapon security etc. abounded with those guys and girls, who were supposedly trained.
I'm very pro-training, but anti-government mandated training.
I think the best firearms training, safe gun handling wise, I ever got was when I took the rifle merit badge as a Boy Scout. And that curriculum was written in part by the NRA.
